Project Design And Implementation Of Cluster Optimization Scheme For LTE Network In A District Of Zhengzhou

In recent years,mobile communications and related industries have developed rapidly,LTE(Long Term Evolution,the fourth generation mobile communication technology,abbreviated as 4G)has penetrated into people's lives.The three major operators of China Mobile,China Telecom and China Unicom have been developing LTE network construction for nearly 4 years.The LTE network has entered the deep commercial application stage from the experiment network stage.The scale of the network has doubled,and the number of LTE users and data traffic have grown rapidly.The rapid growth in LTE traffic competition in 2017 has been intensified.The launch of the unlimited-flow package has stimulated the enthusiasm of users to use the mobile Internet and is changing the people's Internet usage behavior.The concept of using mobile internet at any time,anywhere and at will is deeply rooted in people's minds.The outburst period of LTE traffic is comming,and the user's demand for the network is rapidly releasing.How to quickly,effectively and comprehensively evaluate the operation and service performance of LTE network,to further improve the quality of LTE network service and improve the user perception,has become an important subject of the research of the major operators,and has important significance for the development of the LTE mobile network market.China Telecom Henan Branch has completed the scale deployment of LTE network in Zhengzhou city and is gradually implementing system optimization.Based on the LTE network optimization project of Zhengzhou science and technology market,this paper studies the cluster optimization scheme of the network,the main contents of the completion are as follows:1.Analyze the network status of Zhengzhou science and technology market cluster,and carry out multidimensional network problem assessment,including MR(measurement report)data,three-dimensional simulation,DT(Drive Test),traffic volume distribution,user complaint and so on,and the concept of value evaluation is introduced.We use the two angles of network maturity and network benefit to evaluate the network,and finally develop a cluster optimization scheme that can maximize the network investment and profit.2.According to the current situation of the network,the design and implementation of the cluster optimization scheme are carried out.Through the construction of macro station,antenna facing irradiation,indoor distribution system and micro station construction,antenna connection and rectification,optimization of weak coverage,optimization of overland coverage,optimization of adjacent area leakage,interference elimination and so on,the Zhengzhou science and technology market cluster is designed and implemented in a three-dimensional and comprehensive way,which has been effectively promoted.The network quality of the cluster reaches the expected effect.3.The characteristics and advantages of different frequencies in Zhengzhou technology market cluster are analyzed.The multi frequency cooperative networking strategy is studied from two perspectives,which are based on business perception and covering coverage.The relationship between different types of business perception and the coverage rate of RSRP,the coverage rate under different strategies and the download rate are compared.A comprehensive scheme of multi frequency cooperative networking is developed to maximize the characteristics and advantages of different frequencies and improve the overall service performance of the network.
